LSR liquid silicones for Liquid Injection Moulding

Silicones for LIM procedures (Liquid Injection Moulding) are standard two component liquid silicones. LSR crosslink under heat impact at a mixing ratio of 1:1 through polyaddition with a platinum catalyst.

Their unique processing properties make LSR appropriate for numerous industrial fields and most versatile application fields.

The CHT products of the ALPA-LSR series crosslink without byproducts and offer extraordinary mechanical properties. Due to the low compression set ALPA-LSR products are the ideal components for producing complex shapes.

You can soon find the ALPA-LSR product series in our Productfinder, too. In the meantime, we will be pleased to support you with personal advice on products and application procedures.

ALPA-LSR products stand out for the following excellent properties

  • High dimensional stability
  • High temperature resistance (- 50 to + 200 C)
  • High elongation and flexibility even at temperatures far below 0C
  • Hydrophobic behaviour
  • High UV and weather resistance
  • High ozone resistance
  • Good mechanical and damping properties
  • No outgassing reaction products
  • Mouldings with complex shapes are possible
  • Effective production of high quantities by means of short cycles
  • High transparency
  • Suited for food contact (complies with FDA and BfR)

LSR injection moulding procedures score in several aspects in comparison with classic thermoplastic injection moulding procedures

  • Higher heat stability up to 230 C
  • Low viscosity which facilitates a simple and quicker processing
  • Higher elongation and tensile strength
  • Suited for medical applications and for contact with human tissues
  • Detailed mouldings are possible
  • Production of smallest pieces is possible
  • Quick crosslinking as soon as components A & B have been blended
